Size
The size of the projector screen in inches. Along with the aspect ratio (see below), this parameter is one of the main ones for determining compatibility with the projector: it is necessary that the screen size fit into the range of image sizes that the projector provides. The hit may not be 100%, it is allowed to use a screen slightly larger than the maximum image size from the projector; but if the screen is smaller than the minimum image size, you should not use it — the image will extend beyond its edges.
It is also worth choosing a screen size, taking into account the size of the auditorium and the distance to the audience. For more information about this, see "Screen height", here we note that the larger the room and the farther the audience sits from the screen, the
larger the size you will need. At the same time, a screen that is too large will not always be the best solution: it is inconvenient to look at it close up, and it will take a lot of space to place it.
Screen width
Dimensions of the operating area of the screen in width.This parameter determines, first of all, the free space required to install the screen in the room. Another point is the selection of the distance to the first row of viewers: it should be at least one screen width (but less than two heights). Formally, the width of the screen also affects compatibility with the projector, but in fact this point is determined by the size and aspect ratio (see above), while the width in this case is secondary.
Screen height
Dimensions of the operating area of the screen in height. This parameter is important primarily for selecting the optimal model, taking into account the distance to the audience: it is believed that, ideally, the height should be at least 1/6 of the distance from the screen to the last row. Also, similarly to the width (see above), the height determines the dimensions of the screen and, accordingly, the minimum space required for it in the room, and also to a certain extent affects compatibility with the projector.
